I bought it about a month ago and its been running fine. I took it on a short road trip. It was running great on the way there, but on the way back it started having problems. I started to drive on i-95. I started to accelerate to 70 MPH and it started slipping. Once I was going 70 it would idle up and down without me pushing on gas peddle. I checked the trans fluid when I got home and it is brown and smells burnt. Do I need a new transmission or is there something else I can do? Thank you.
